Silicon powder manufacturer is a non-toxic, odorless, non-polluting inorganic non-metallic material. Because of its excellent properties such as good temperature resistance, acid and alkali corrosion resistance, high thermal conductivity, high insulation, low expansion, stable chemical properties, and high hardness, it is widely used in chemicals, electronics, integrated circuits (IC), electrical appliances, Plastics, coatings, paints, rubber, national defense and other fields. With the rapid development of high-tech fields, silicon powder will also enter a new historical development period.

The micro-silica fume can fill the pores between cement particles, and at the same time form a gel with the hydration product, and react with the alkaline material magnesium oxide to form a gel. In the cement-based concrete, mortar and refractory castables, mixing a proper amount of silica fume can play the following roles:

Significantly improve the compression resistance, flexural resistance, impermeability, corrosion resistance, impact resistance and wear resistance.

It has the functions of retaining water, preventing segregation, bleeding, and greatly reducing the resistance of concrete pumping.

Significantly prolong the service life of concrete.

Significantly reduce the floor ash of sprayed concrete and castables, and increase the thickness of a single spray layer.

It is a necessary component of high-strength concrete, and C150 concrete has been used in engineering.

It has about 5 times the effect of cement, and can reduce costs and improve durability when used in ordinary concrete and low cement castables.

Effectively prevent the occurrence of concrete alkali aggregate reaction.

Improve the compactness of castable refractories. When coexisting with Al2O3, it is easier to form a mullite phase, which increases its high-temperature strength and thermal shock resistance.

The above is a brief introduction by the editor for the manufacturers of silica powder to effectively prevent the occurrence of concrete alkali aggregate reaction. You can simply understand it.
